The alterations were amazing in that they made this dress one of kind. I had the back lowered and shaped into a V cut to show more of my back. The best part of the alterations was how I had the seamstress cut the dress mid thigh to make it a cocktail dress for the reception! This dress is 2 dresses in one! They did such an phenomenal job with this. It was a surprise to everyone as, I just changed dresses so quickly by just simply unzipping the bottom. It has a perfectly hidden zipper that unfastens the entire bottom half, and it was very easy to use. For the chest area, there are 2 internal clips that were added in to hold any bra you decide to wear. They hold the bra to the dress if you decide, or you can just easily not use them. This is mainly so that if you are moving around the bra won't show and holds the bra in place.
